What are the hazards of living in a house with formaldehyde?

The health hazards of formaldehyde mainly include the following aspects:

1. irritation: the main harm of formaldehyde is the irritation to skin and mucosa. Formaldehyde is a toxic substance in protoplasm, which can combine with protein. When inhaled in high concentration, severe respiratory irritation and edema, eye irritation and headache may occur.

2, sensitization: direct skin contact with formaldehyde can cause allergic dermatitis, pigmentation, necrosis, inhalation of high concentration of formaldehyde can induce bronchial asthma.

3. Mutagenesis: High concentration of formaldehyde is still a genotoxic substance. Experimental animals can cause nasopharyngeal tumors under the condition of high concentration inhalation in laboratory.

4. Outstanding manifestations: headache, dizziness, fatigue, nausea, vomiting, chest tightness, eye pain, sore throat, loss of appetite, palpitation, insomnia, weight loss, memory loss and autonomic nervous disorder. Long-term inhalation by pregnant women may lead to fetal malformation or even death; Long-term inhalation by men will lead to male sperm deformity and death.

Method for removing formaldehyde

1, removing formaldehyde by ventilation

Through the circulation of indoor air, the content of harmful substances in indoor air can be reduced, thus reducing the harm of such substances to human body. People often close doors and windows in winter, so the indoor and outdoor air can't circulate. Not only the content of formaldehyde in indoor air will increase, but also radon gas will accumulate continuously, even reaching a very high concentration.

2. Plant deodorization method

Plant decontamination can be selected for medium and low pollution: generally, indoor environmental pollution is light and moderate, and the pollution value is less than 3 times of the national standard. Using plants to decontaminate can achieve better results. Choose and place plants according to different functions and areas of the room. Generally speaking, it is more appropriate to put two pots of plants with a height of 10 square meter in a room with a height of10 meter.

3. Activated carbon adsorption method

Activated carbon is an internationally recognized expert on drug abuse. Activated carbon masks and gas masks are made of activated carbon. The product uses the physical function of activated carbon to deodorize and detoxify; No chemical additives, no influence on human body. Put two or three dishes in each room, and 72 hours can basically eliminate indoor odor. This method can be used for medium and low pollution, and can also be combined with other chemical methods, which has a better comprehensive control effect on decoration pollution.
